Why a fan accused of throwing a water bottle at Kyrie Irving was charged with assault

A fan wearing a Boston Celtics jersey was arrested and charged with assault and battery with a dangerous weapon after allegedly throwing a water bottle at Brooklyn Nets star Kyrie Irving on Sunday night. Many basketball fans online questioned whether throwing the plastic bottle actually constitutes assault, but law experts say the charges are common and a conviction would come down to proving the suspect's intent to cause bodily harm.
